Abstract: Abstract of the Disclosure The invention provides a method for the secondary recovery of oil from an oil-bearing stratum having a zone of high fluid permeability, in which this zone is plugged by introducing into the stratum a gelable solution comprising an alkaline material, a polyphenolic vegetable material such as mimosa tannin extract and formaldehyde, the last compound being present as free formaldehyde para-formaldehyde or a phenol-formaldehyde resole. The gelable solution has a pH of at least 9.5 and may optionally include a viscosifier. The gelable solutions are relatively insensitive to brines or temperature and gel to produce mechanically strong gels, even in the presence of oil-wet minerals. If desired, the alkaline material can be an alkali metal carbonate, and the use of such carbonates permits the permeability of the plugged high permeability zone to be adjusted after formation of the gel by treating the gel with acid.

Abstract: Abstract A face milling tool is described including a holder securable to the end of a rotatable spindle.  Cutting inserts are detachably secured to the end face of the holder at a radial distance from the axis of the spindle.          The cutting edges of the inserts extend outwardly of the holder end face such that the cutting edges are free to engage and machine the surface of a workpiece.  The inserts are of a wafer-like form and means are provided for detach-ably securing the inserts to the holder through a central axial aperture in the inserts.  The securing means lies within the outer end face of each insert and the cutting edge of each is substantially straight, being formed by a portion of an edge at the intersection of the insert side wall and the end face.  Each insert lies at such an angle to the plane of the workpiece that the insert side wall forms a rake face and the outer end face of the insert forms a clearance face and the straight cutting edge lies at a small radial shear angle.  The inserts are circum-ferentially spaced around the holder and are axially and radially stepped to form both an axial and radial progres-sion, whereby each insert removes a shallow uniform work-piece chip and the material is removed progressively from the top surface of a workpiece down to a finished surface in controlled, shallow, axial increments of less than 0.01 inch.

Abstract: Abstract of the Disclosure A novel flow divider-combiner valve unit is disclosed.          A valve body includes fluid passageway means for con-trolling fluid flow through the divider-combiner valve unit.  The fluid passageway means comprises: a cavity, first, second and third passageways; first and second pressure-responsive elements; and biasing elements for retaining the pressure-responsive elements substantially in open positions until a predetermined substantial pressure differential exists in the divider-combiner valve unit.  The biasing elements also enable the pressure-responsive elements to move substantially independently of each other toward closed positions when a first pressure differential in the divider-combiner valve unit exceeds the predetermined pressure differen-tial.  The biasing elements additionally cause the pressure-responsive elements to move substantially in unison when a second pressure differential in the divider-combiner valve unit exceeds the predetermined pressure differential.  The first and second passage-ways communicate with first and second spaced portions of the cavity.  The third passageway communicates with an intermediate portion of the cavity.  The first and the second pressure-responsive elements are movable in the cavity respectively between first open positions and progressively closed positions.  The fluid passage-way means controls fluid flow through the divider-combiner valve unit by controlling fluid flow between the first and the second cavity portions and the first and the second passageways.

Abstract: ABSTRACT     The present invention relates to the replacement of an existing main, particularly an existing cast iron gas main, with a new main utilizing a device in the form of a mole.          The mole 1, which is of steel, is adapted to be inserted into and moved along the existing main 8.  The mole 1 has a front portion comprising a head 2 and a cylindrical body portion 3 and a rear portion having clamping means 4 for clamping a new main 13. The head 2 has a cutting face 5 for engaging the internal wall of the exiting main 8 so as to cause the wall to fracture as the mole 1  moves therealong.  Th new main 13 which in use is clamped to the mole 1 is towed along behind the mole 1 to replace the fractured old main 8.  In one embodiment of the invention (Figure 1) the cutting face 5 comprises three or more cutting edges 6 formed by grinding of high tensile steel cutters 7 which are located in keyways in the head 2. In another embodiment of the invention (Figure 4) the cutting face 25 may comprise  three or more pivotally mounted cutting blades  26 which are pivotally mounted at their forward ends 27 to the wall of the head 23.  The blades 26 are caused to pivot radially outwardly from their closed position to engage the pipe wall 45 and fracture it as the mole moves along the pipe towing the new main 43 therewith.     In still another embodiment of the invention, (Figure 10) only one 58 of the blades is pivotally mounted at its forward end 59 to the mole 51, the other blade 56, 57 being fixed.  In this embodiment, the mole 51 is driven through the existing main 94 by means of a pneumatically actuated hammer 80 (Figure 8) engaging percussively with an internal wall of the mole formed by an internal bore 82.          The pivotal blade 58 pivots under the action of an associated piston 64 which is hydraulically actuated by fluid supplied from a hose 103 by way of a channel 70.  The blade 58 is normally closed but is pivotted to fracture any circumferentially located obstruction located in the main 94 and serving to inhibit the movement of the mole 51 therethrough.
